JOHN D. LAUERMAN, OF LAKE HOPATCONG, NEW JERSEY.

PARTINGr-STRIP FOR WINDOVS.

Application filed. June 27, 1818.

To all whom it may concern:

Be it known that I, JOHN D. LAnnRMAN, a citizen of the United States, residing at Lake Hopatcong, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Parting-Strips for WVindows, of which the following is a description.

ihis invention relates to window construction, particularly to parting strips, and has for its object the provision of a parting strip which is so constructed and associated with the window frame that it will always be urged resiliently into close engagement with the sash, whereby the parting strip will not only serve as a weather strip for excluding moisture and draft but will also prevent rattling of the sash and sticking thereof.

An important object is the provision of a parting strip of this character which will not only be extremely simple and inexpensive in manufacture and installation, but which will be highly durable and efficient in use, and a general improvement of the art.

With the above and other objects in View, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which:

Figure 1 is a cross sectional view through one side of a window casing showing the improved parting strip applied and engaged by a sash,

Fig. 2 is a longitudinal sectional view, and

Fig. 3 is a detail view.

Referring more particularly to the drawing, the numeral 5 designates one side of a window casing embodying the usual pulley stile 6, outer or blind stop 7, and the inner stop 8. A sash is indicated at 9.

My invention is designed to take the place of the usual parting strip and is disposed within a longitudinal groove 10 in the face of the stile 6. In carrying out my inven tion, I employ a channel bar 11 which is U shaped in cross-section and which has its sides disposed within the groove 10 in snugly fitting relation thereto. The outer closed side, or bight, of this channel bar is disposed substantially flush with the face of the stile as clearly shown. This channel bar is formed of metal, preferably galvanized iron on account of its non-corrosive nature.

The strip proper which I employ in con- Specification of Letters Patent.

Patented nee. as, rai Serial No. 242,177. I

nection with the channel bar 11, is desi nated by the numeral 12 and is formed as a wooden strip loosely connected with the bar 11 by a plurality of screws 13 which are threaded into the strip 12 and which have horizontally disposed flat heads it passed through slots 15 in the closed side of the bar 11. The heads 14 are provided with slots 16 in which are disposed leaf springs 17 which are bowed away from the closed side of the channel bar at their intermediate portions with their ends engaging thereagainst. The strip 12 is formed as a parallelogram in cross-section so that when one edge is disposed fiat against the closed side of the bar 11 the side edges will be laterally inclined in respect to the sides of the bar with one side edge projecting into a plane outwardly of the adjacent side of the bar 11 as clearly shown.

From the foregoing it will be seen that the lateral rocking movement of the strip 12 .is permitted but resiliently opposed as such movement causes the heads 14 of the screws 13 to engage and tend to compress the springs 17 When my parting strip structure is applied to a window casing, as shown, the sash 9 will engage the edge 18 of the strip 12 and consequently rock the strip 12 upon the edge 19 as a fulcrum. As this movement of the strip is opposed by the springs 17, it will be obvious that the strip 12 always bears against the sash with sufficient resilient firmness to insure a close but sliding contact whereby the strip will perform the functions of a weather strip by excluding rain or coid drafts, while the sash will of course be capable of sliding movement.

Vhile I have shown and described my in vention as applied to only one of a pair of upper and lower sashes, it will of course be understood that it would be applied in the same manner to both sashes.

Having thus described my invention, 1 claim:

1. In a window structure including a casing and a sash associated therewith, each inner side face of said casing being provided with a longitudinal groove, a parting strip comprising a channel bar disposed in said groove with its closed side outermost, a strip rockably engaged upon said channel bar and spring means engaging said strip and said channel bar for urging said strip lateraily into engagement with the sash.

2. In a window structure including a casing and a sash associated therewith, a parting strip comprising a channel bar disposed within a groove in the inner face of each side of the casing with its closed side outermost, a strip rockably engaged upon the outer closed side of said channel bar and formed as a parallelogram in cross-section with one outer side edge disposed laterally beyond one side of said channel bar in engagement with the sash, a plurality of bowed leaf spring members disposed within said channel bar with their ends in engagement with the closed side thereof, and members engaging said spring members and extending into said strip, whereby movement of the strip away from the sash will be resiliently opposed.

In testimony whereof I hereto aflix my signature.

JOHN D. LAUERMAN.
